OBJECTIVE: To assess Malaysian dental therapists' perceptions of their job satisfaction and future roles.
METHODS: A nationwide postal survey involving all Malaysian dental therapists who met the inclusion criteria (n = 1726).
RESULTS: The response rate was 76.8%. All respondents were females; mean age 35.4 years (SD = 8.4). Majority were married (85.5%) and more than one-half had a working experience of <10 years (56.1%). Majority worked in community dental service (94.3%) and in urban areas (61.7%). Overall, they were highly satisfied with most aspects of their career. However, they were least satisfied with administrative workload (58.1%), career advancement opportunities (51.9%) and remuneration package; specifically income (45.2%), allowances (45.2%) and non-commensurate between pay and performance (44.0%). Majority perceived their role as very important in routine clinical tasks such as examination and diagnosis, preventive treatment, extraction of deciduous teeth and oral health promotion. However, fewer than one-half consider complex treatment such as placement of preformed crowns on deciduous teeth (37.1%) and extraction of permanent teeth (37.2%) as very important tasks.
CONCLUSION: Majority expressed high career satisfaction with most aspects of their employment but expressed low satisfaction in remuneration, lack of career advancement opportunities and administrative tasks. We conclude that most Malaysian dental therapists have positive perceptions of their current roles but do not favour wider expansion of their roles. These findings imply that there was a need to develop a more attractive career pathway for therapists to ensure sustainability of effective primary oral healthcare delivery system for Malaysia's children.
The window of maximum susceptibility for the development of dental fluorosis for anterior
teeth is during the first two to three years of life. The primary source of fluoride intake for
infants at this age is mainly from the diet including infant formula. Thus, the present work
aimed to investigate the fluoride concentration in commercially available Malaysian infant
formulas that required reconstitution before consumption. A total of 29 infant formulas available in the Malaysian market were reconstituted with deionised water, fluoridated tap water,
and filtered tap water. The fluoride concentration of the infant formulas was analysed directly
using a fluoride ion selective electrode. The daily fluoride intake estimation from the infant
formulas was calculated using the median infant body weight and recommended volumes for
formula consumption from newborn to > 12 months of age. Results showed that the fluoride
concentration of the infant formulas when reconstituted with deionised water ranged between
0.009 to 0.197 mg/L that contributed to the estimated daily fluoride intake ranging from 0.005
to 0.100 mg (total intake per day) or 0.001 to 0.025 mg/kg (total intake per body weight/day).
The fluoride concentration in the selected infant formulas was low, but after reconstitution
with fluoridated tap water, the overall fluoride concentration in infant formulas sample significantly increased (p < 0.001). Nevertheless, the estimated daily fluoride intake from infant
formulas alone did not exceed the lowest-observed-adverse-effect level (LOAEL) of fluoride
at 0.10 mg/kg/day.
